The LM3S328-IQN25-C2 is a 32-bit ARM Cortex-M3 MCU from the Stellaris 300 series, clocked at 25 MHz with 16 KB of Flash and 4K x 8 of SRAM. It carries 28 GPIOs, an 8-channel 10-bit ADC, and serial interfaces including I²C, SPI, SSI, and UART/USART.
The LM3S328-IQN25-C2 is marked obsolete by Texas Instruments. No last-time-buy window remains open through the factory channel.
The core runs at 25 MHz, which is the maximum clock for this Cortex-M3 implementation in the Stellaris 300 series.
